Will this system bolt directly to my factory cat, or do I need an adapter?

The system connects at the factory catalytic converter outlet — no adapter needed. Check the factory connection size before ordering to confirm fitment.

Do I need to have this ceramic coated or painted?

Stainless steel requires no coating or paint. Out of the box it resists corrosion and oxidation. You can polish it to a mirror shine if you want it brighter.

What hardware comes with this exhaust?

The system includes the cat-back assembly with clamps and gaskets for the factory connection point. Verify your existing bolts are reusable before installation.
